PFS7636H

Overview

The PFS7636H is a HiperPFS-4 device from Power Integrations, integrating a continuous conduction mode (CCM) boost power factor correction controller, gate driver, and a 600 V power MOSFET into a single low-profile package with the ground pin connected. It eliminates external current sense resistors to reduce power loss. The device utilizes an innovative control technique that adjusts switching frequency based on output load, input line voltage, and input line cycle to maximize efficiency across the entire load range, particularly at light loads. This wide bandwidth spread spectrum effect minimizes EMI filtering requirements.

Feature Summary

• Integrates CCM boost PFC controller, gate driver, and 600 V power MOSFET in a single low-profile package.
• Eliminates external current sense resistors and associated power loss through innovative control techniques.
• Adjusts switching frequency over output load, input line voltage, and input line cycle to maximize efficiency.
• Minimizes EMI filtering requirements via wide bandwidth spread spectrum effect.

Applications

• High-efficiency power factor correction stages
• Lighting applications requiring high PF
• Consumer electronics power supplies
• Industrial power supplies

Procurement Notes
